Turns out the leak could be worth over $10 billion in damages, according to a brand new lawsuit filed today by Tony Buzbee.

Here's an excerpt:

In this case, tens of thousands individuals were injured and had his or her long-term health put in jeopardy after being exposed to extremely high levels of Benzene and other toxic chemicals while working at the BP Texas City Refinery or by simply living or working in Texas City. Plaintiffs and all members of the Class, the Worker Sub-class and the Texas City Sub-class seek remedy for this exposure, and also attempt to do, through this case, what none of the authorities thus far has been able to do—put an end to BP’s continuous pollution of the air, ground, and water, and the continued exposure to harmful substances of workers at the BP Texas City Refinery. In this effort, Plaintiffs seek punitive damages against BP in excess of $10 billion.

How significant is $10 billion? A huge blow if Buzbee can get anywhere close -- nearly half as costly in damages as the oil spill, according to estimates by Citi. Which is to say we'd all be shocked if it turns out that bad.
